It's clear to me, too, but then again, I decided on the format ;-)
Karl does have a point that the format of the confirmation mesasge has
changed, and that it may not be quite as straightforward as the old format.
I made the change in preparation for when FX is powered by a new back-end
that supports to idea of conditional claims. In other words, it will be possible
to buy and sell shares in a claim that are backed not with FX$ but the shares
of another claim. For example, two people may trade in Claim2, using shares
in Claim1 as collateral. This allows us to explore "what if" scenarios -- e.g.,
what are the odds of Claim2 coming true, *if* Claim1 is assumed to be true?
One effect of trades of this nature is that it seems to make sense to structure
the transaction summary as a list of what holdings have changed, as is done above.
However, I'm always open to suggestions...
